Patented Mar. 25, 1930 UNITED- STATES PATENT oFFicE' AUGUST F. OSTERLIND, OF ST. PAUL, MINNESOTA; FRANK OSTERLINDAND JOHNv A. JACOBSON ADMINISTRATORS OF SAID `AUGUST F. OSTERLIND, D'ECEASED METHOD on ivrAxTNG CALENDARS Application .led July 28, 1927, Serial No. 209,010. Renewed September 12, 1929.

It is the present general practice in the printing and binding of calendars to prlnt the several units, such as the months of the year, upon separate sheets and then to manually gather the sheets into groups, each of which, contains the sheets required to make up a completecalendar pad and then to bind the sheets of each pad together. n .Y

With this method, a large part of the cost of the calendar is represented by the item of labor required for the gathering ofthe leaves together preparatory to binding.

It is my object to reduce the cost of manu' facturlng calendars by eliminating the hand work heretofore required in gathering of the printed sheets into groups.

In the method of this invention, I print all of the units or calendar months for each calendar on a single integral sheet. The several units are arranged inte two groups, one group being printed on one side ofthe sheet and the other on the opposite side, leaving blankspaces upon the proportions of the sheet lo-- cated directly Subsequently, the sheet so printed is folded in a suitable machine or otherwise to form' a calendar pad and. finally the margins ofthe .pad are trimmed to-free the individual units or leaves and the leaves are bound in any suitable or well known man Y er. In the following specification, I have d scribed an arrangement of the units on a sheet,w hich is adapted for use with a folding machine of common t e. yllheinvention will he be'st understood by reference to the accompanying drawings in which Figure 1 is a diagrammatic lan view showing a suitable arrangement o the several units constituting a calendar pad upon a single sheet; Figs. 2, 3, 4 and 5 illustrate the same sheet after the first, second, lthird and lfourth folds respectively, Figshowing the sheet ready for trimming and Fig. 6 shows diagrammatically a suitable la'yout of a unit whereby a plurality of calendars of different sizes and shapes may beprepared in a single folding operation by following my improved method. f

In carrying out my invention, two print- 5o ing presses may be employed, the type necesv each month is to be manufactured, the monthback of each unit or month.

. it into leaves,

sary for rintingone-half the units of the,` calendar being set up on one press andthe other half upon the other press. Thus, where. a pad of the common type having a leaf for ly units representing six months may be arranged for printing, as indicated in full lines in Fig. l upon one press and the units for 'the `other six months of the year maybe set up on the other press.` The units indicated in full lines in Fig. 1 are printed on one side of the sheet and the units indicated in dotted lines are printed on the reverse side by passing the sheet through the other press. It will be noted thatportions of the sheet directly back of each unit are'left blank. In other words, the several units upon one .side of the sheet are spaced apart and the units printedupon the opposite side of the sheet. register with the spaces on the reverse side.

- Now the printed sheet may v be passed through a folding machine to produce al ad, as indicated in Fig. 5, having a super cial area approximately equal to the size of one of the units. With the arrangement shown in Fig. 1,"the first fold is along a vertical line, indicated byl the numeral 7 and ex-4 tendingacross the sheet. This produces -a sheet likethat shown in Fig. 2. The second fold is along a horizontal, dotted line 8, shown in Figs. 1 and 2, andresults'in-reducing the sheet to the form shown in Fig. 3. The third fold is along a vertical line 9 and the fourth along the horizontal line 10 to successively produce'the forms shown in Figs. Ltand 5. 85 The several units arenow disposed in proper' sequence, one upon another, and a pad having a superficial area the size of one of the 'units results. This pad is now trimmed along4 the lowerleft and right edges to separate each 'leaf bearing the printed representation of a month or other unit. Finally, the vpad is bound in any suitable or well known manner and the calendar is come plete. y 4 i Similar procedure l may he followed to print two calendars by the use of a single press. Thus, typeor plates for printing the several units of a complete calendar may be set up on one press With the units in spaced 10Q relation, as indicated in Fig. 1, and then one side of the sheet is printed. The sheet is now reversed and a complete calendar printed upon the other side upon the portions of the sheet which register with the spaces between the first printed units. The sheet so printed is then cut into halves, each similar to that shown in Fig. 1. The subsequent procedure in folding, trimming and binding is like that above described.

Where it is desired to print a plurality of calendars of different sizes and shapes, each unit of a printed sheet divided like that above described, may be arranged to constitute the corresponding unit o f a plurality ofv calendars and in such case each unit may be divided', as indicated in Fig. 6. After printing and folding of the sheets having units like that indicated in Fig. 6, the folded pad may be cut into a plurality of calendars by cutting along the lines 11, 12 and 13.

Obviously, where the sheet is tolbe folded differently from that described, a different arrangement of the units is required in order to avoid rearrangement of the leaves after folding.

It will be understood that where the term unit is used in the following claims, it is intended to include any suitable division of the calendar year, such as the month, or a shorter period, or a plurality of months,

which maybe desired upon a leaf of thev calendar.

Claims:

1. The method of making calendars which consists in printing upon an integral sheet a plurality of -units arranged in two groups, the units of one group eing disposed in spaced relation to each other andthe units of the other group being printed on the re? quired to make a calendar, the units being. disposed in spaced relation to each other, then printing upon the reverse side of said' sheet a similar group of-units, the units of the second group being printed in registry with the spaces between units of the first group, then cutting'said sheet to form two calendar sheets, subsequently folding each of said sheets twice horizontall and twice vertically to form pads, each aving a superficial area approximately equal to the size of one unit and then separating at least some of the edges of the units to form the leaves of two calendar pads.

In testimony whereof, I have hereunto signed'my name to this application.
